Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing reel, and more particularly to a fishing reel provided with a drag mechanism that generates a drag force by contact between friction plates.

[0002]

2. Description of the Related Art Drag mechanisms that generate a drag force due to contact between friction plates include those having two friction plates and those having three or more friction plates.
Used in all fishing reels. Further, some of such friction plates use one of a body and a gear or a spool as a friction surface.

The structure of these drag mechanisms is basically the same regardless of the type of fishing reel, and the drag mechanism having two friction plates is of the same type as a cork material. One friction plate (drag plate) made of a synthetic resin material or a metal material, and the other friction plate (contact plate) made of a metal material. A drag force is generated by being brought into contact with and separated from the other by operation of the adjustment unit, and the strength of the drag force is adjusted. A drag mechanism having a large number of three or more friction plates has a friction plate (contact plate) that idles on both sides of a friction plate (drag plate) that rotates integrally with a spool or a handle. The friction plate (contact plate) is configured to generate a drag force by holding a friction plate (drag plate) by operating a drag force adjustment unit such as a lever or a handle, or to adjust the strength.

[0004]

The drag mechanism is an extremely important mechanism for reliably and quickly catching fish, and the performance of the drag mechanism can be said to be the performance of a fishing reel. is not. For this reason, each manufacturer has determined that the pulling force of the fish exceeds the set drag force, and at the same time, the friction plates smoothly slide out from each other, and that the sliding continues extremely smoothly. We have developed a variety of drag mechanisms that can reliably exert the resultant force and securely stop the fishing line being fed.

[0005] For example, the material of the friction plate is changed, the range of change in contact force is widened, and the drag mechanism is waterproofed with a waterproof cover so that water does not enter the contact surface between the friction plates. A drag mechanism that achieves the above effect is realized.

[0006] In particular, in the case of the one waterproofed with a waterproof cover, water does not enter between the friction plates, so that slippage between the friction plates is hindered, resulting in a jerky slip or a pulling force exceeding a set value. Even if it doesn't slide out or slides out before it is over, it has been resolved.

However, since the waterproof cover has a perfect watertightness and it is necessary to minimize the influence on the operation of the fishing reel and the drag mechanism, it is very difficult to form and assemble the waterproof cover. In addition to those that are difficult and use grease, packing, etc., they need to be regularly replaced or replenished. Also, the maintenance of the drag mechanism may take a very long time because it is completely covered by the waterproof cover. Furthermore, when water enters the waterproof cover for some reason, it cannot be released unless it is decomposed, so if water enters during actual fishing, it will continue to be used in that state, that is, the operation of the drag mechanism is inhibited. Not get. Furthermore, in such watertightness, a frictional force is generated between a watertight member such as grease or packing or a holding portion of a waterproof cover holding the watertight member and the rotating member, so that the drag force is reduced to 0 ( (Drag-free) state may cause a problem that free rotation of the spool (spool-free) is hindered. Therefore, there were complaints such as an increase in cost due to an increase in the number of manufacturing steps and the number of parts in the manufacture of the fishing reel, difficulty in maintenance, and inability to drain water during actual fishing.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional circumstances, and has as its object the purpose of the present invention is to use a fishing mechanism in which a drag mechanism can be operated accurately without using a new member such as a waterproof cover. To provide a reel.

[0009]

In order to achieve the above-mentioned object, the present invention employs a completely reverse conception of the conventional waterproofing means, that is, a technical means for immediately draining invading water. did.

[0010] The technical means is that in a fishing reel provided with a drag mechanism in which a drag force is generated by contact between the friction plates, water penetrating into the contact surface between the friction plates is applied to the friction plates. A centrifugal force due to rotation or a surface pressure generated between the friction plates, or a drainage portion that allows drainage by the interaction between them, prevents water from remaining on the contact surface and accurately operates the drag mechanism. That's what we did.

According to this technical means, a centrifugal force is generated on the friction plate which rotates with the rotation of the spool and the handle. The centrifugal force acts on the water that has entered the contact surface between the friction plates, and drains the water to the drain. In addition, the surface pressure generated between the friction plates acts to push out water that has entered between the friction plates from between the friction plates, and drains water to a drainage portion. Further, when the centrifugal force and the surface pressure interact with each other, the centrifugal force acts on the extruded water, thereby improving drainage efficiency. This prevents water from remaining on the contact surface, so that the drag mechanism operates correctly.

As a specific configuration of the drain portion, a drain groove for storing water invading between the friction plates is formed in one of the opposed friction plates along the circumferential direction of the friction plate. What is formed by forming it. According to a fourth aspect of the present invention, there is provided a drainage channel formed with a drainage channel for draining water accumulated in the drainage channel from the drainage channel to the friction plate.

According to the technical means of the third aspect, most of the water that enters between the friction plates is stored in the drain. In addition, the water overflowing the drain reaches the center between the friction plates, but the water is discharged to the drain by centrifugal force or surface pressure generated by rotation of the friction plates. Further, according to the technical means of the fourth aspect, the water stored in the drainage drain is drained out of the friction plate from the drainage channel.

Since the drain groove is formed in an annular shape along the periphery of the friction plate, it does not affect the contact rotation between the friction plates at all. Further, the contact between the friction plates is performed on the surface excluding the drain groove to generate a drag force.

The form of the drainage channel may be any form such as a hole or a notch as long as it can drain water.
The disposition position may be any position in the drain groove (bottom portion, outer side portion) and a position where the drain groove can communicate with the outside of the friction plate. Also,
The number and size of the drainage channels are arbitrary as long as the rigidity of the friction plate and the drainage efficiency are ensured.

For example, when the drainage channel is provided as a hole at the bottom of the drainage groove, the drainage channel may be parallel to the axis of the friction plate, or may be inclined with respect to the axis in the direction in which water is drained. If it is parallel to the axis, there is an advantage that the formation is extremely simple, and if it is the above-described inclined shape, there is an advantage that water on which centrifugal force acts is easily drained.

In the case of arranging it on the side, it may be parallel to the center line in the radial direction, or may be inclined relative to the center line in the direction opposite to the rotation direction. If the shape is parallel to the center line, there is an advantage that the formation is extremely simple. If the shape is inclined as described above, there is an advantage that water on which centrifugal force acts is easily drained. In the case of disposing on this side, a hole or a notch may be used, but a notch is desirable from the viewpoint of securing an arrangement space.

The drainage groove may be one or more,
If a plurality of drainage grooves are provided as in claim 5, it is extremely efficient to collect and drain the intruding water. The plurality of drain grooves may have the same width or may have different widths. In addition, the number is arbitrary as long as the rigidity of the friction plate is maintained and a contact surface that does not impair the drag force is secured. Specifically, there are two drain grooves that are wide on the outside and narrow on the inside.

According to the technical means of the fourth aspect, water overflowing from the first drainage ditch enters the second and subsequent drainage ditch and is drained from each drainage channel.

The position of the drainage groove is arbitrary. However, most of the contact force is generated at the contact surface from the center due to deflection or the like generated when the friction plates contact each other. Since the outside is the strongest, it is optimal to dispose the drain groove near the outer periphery of the friction plate as in claim 6.

According to the sixth aspect of the present invention, it is possible to effectively drain the water that has entered due to centrifugal force or surface pressure without lowering the drag force, and to operate the drag mechanism accurately. Can be.

In order to achieve more accurate operation of the drag mechanism, it is preferable to suppress the flexure of the friction plate together with the presence of the drainage portion. In the case where the same drainage portion as that of the first embodiment is provided and the drag mechanism is composed of two friction plates, a flange portion is formed along the axial direction of the friction plate along the entire circumference of one of the two friction plates. When the drag mechanism is composed of three or more friction plates, the flange portion is provided on both or both of the outer friction plates, or on the entire outer periphery of one of the friction plates. To prevent the water from remaining on the contact surface and to accurately operate the drag mechanism.

According to this technical means, the deflection of the friction plate due to the contact between the friction plates, particularly from the outer periphery, is suppressed by the flange portion, and the same surface pressure can be secured over the entire friction plate. it can. Furthermore, if the deflection from the outer periphery that bends most is suppressed, the occurrence of a gap on the outer periphery is prevented, and the amount of water entering between the friction plates can be greatly reduced. To play.

The friction plate is coated with grease to realize smooth sliding. To prevent the grease from running out, either one of the opposing friction plates, or
It is preferable to provide a grease reservoir on both sides so as to replenish the grease that is insufficient when the contact rotation is performed. This grease also greatly contributes to the water repellency of the intruding water.

[0025]

The fishing reel of the present invention is provided with a drag mechanism that generates an accurate drag force by a configuration that was not present at all at the present time of draining by centrifugal force or surface pressure.
No member constituting the conventional waterproof structure is required. Thereby, dissatisfaction with the fishing reel having the conventional waterproof structure can be eliminated. Therefore, a fishing reel that maintains accurate drag performance without maintenance for a long period of time can be provided at low cost.

According to the second aspect of the present invention, in addition to the effect of the first aspect, by suppressing the flexure of the friction plate, the same surface pressure is secured over the entire area of the friction plates, so that the drag force is reduced. Does not decrease. In addition, since the generation of the gap around the outer periphery of the friction plate is greatly reduced, the amount of water entering between the friction plates is greatly reduced, so that a great effect can be expected in that an accurate drag function is exhibited.

Furthermore, according to the third aspect of the present invention, most of the intruded water can be stored in the drain before reaching the entire contact surface, and the small amount of water that has reached the contact surface can be centrifugal force or friction plate friction. Because it is immediately discharged into the drain by the surface pressure generated
Water that has entered does not remain between the friction plates, especially at the contact surfaces. Further, according to the fourth aspect of the invention, the water collected in the drain can be drained out of the friction plate from the drain channel.

In addition, according to the fifth aspect of the present invention, since there are a plurality of drain grooves, the drain efficiency is greatly improved.

Further, according to the invention of claim 6, since the drain groove is disposed near the outer periphery of the friction plate, the drain efficiency can be further improved without lowering the drag force.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG.
This shows an example of a lever-drag type dual-bearing reel A. The basic configuration is well known and will not be described in detail, but the rotation of the handle 1 is transmitted from the gear train 2 via the drag mechanism 3 to the spool 4. It is to be transmitted to.

In the drawing, reference numeral A1 denotes a spool shaft supported by the left and right frames A2 and A3 to support the spool 4 so as to freely rotate, A4 denotes a disc spring for suppressing the axial movement of the spool 4, and A5 denotes a disc spring. A compression spring that urges a friction plate 33 to be described later to be always separated from the spool 4, and a cam mechanism A6 that converts rotation of a drag lever 32 to be described later into sliding of the friction plate 33 in the axial direction.

The drag mechanism 3 is also of a well-known construction and will not be described in detail. However, a friction plate 31 made of cork affixed to the side plate 41 of the spool 4 (hereinafter referred to as a drag plate) will be described.
The rotation of the gear train 2 is transmitted, and the rotation of the drag lever 32 slides along with the spool shaft A <b> 1 and slides on and away from the drag plate 31. When the drag plate 31 and the contact plate 33 are brought into contact with each other, the rotation of the handle is transmitted to the spool, and the frictional engagement force due to the contact becomes a drag force.

The drag plate 31 is formed with a large number of grease holes 34... 34 for storing grease, and the shortage of grease applied to the drag plate 31 and the contact plate 33 is successively replenished to prevent the grease from running out. are doing.

Reference numeral 5 denotes a drainage portion for draining water that has entered between the drag plate 31 and the contact plate 33. The drain portion 5 is formed on the contact surface 35 of the contact plate 33 as shown in FIGS. 3 and 4, and specifically, an annular drain groove 51 along the outer periphery of the contact plate 33, An annular sub-drainage groove 52 located inside and concentric with the groove, and bottom portions 53, 5 of the grooves;
4, a plurality of drainage channels 55... 55, 56.
6.

The drain groove 51 and the auxiliary drain groove 52 are connected to the right frame A2.
Through the gap between the drag plate 31 and the contact plate 33 through the gap between the drag plate 31 and the contact plate 33. The drainage groove 51 is formed wider than the sub-drainage groove 52, so that most of the entering water is stored. On the other hand, the sub-drain 52 is configured to store water overflowed in the drain 51.

The two grooves are located outside the center between the center and the outer periphery of the contact plate 33, so that the intruding water is immediately stored and the strongest centrifugal force acts on the water. I have. Thus, the contact surface 35 is secured near the center where the contact force acts most, so that water does not easily enter the contact surface 35 and drainage is facilitated.

The drainage channels 55... 55 and 56.
There are four through-holes arranged at an interval of 0 degrees, and the diameter is substantially equal to the groove width, and is formed parallel to the axis of the contact plate 33.

When water enters between the drag plate 31 and the contact plate 33 during use, the water is stored in the drain groove 51, and the water overflowing from the drain groove 51 is discharged from the drain unit 5. It is stored in the sub-drain 52. Water overflowing from the sub-drain 52 reaches the contact surface 34.

In this state, when the handle 1 is rotated, the contact plate 33 rotates to generate centrifugal force. The centrifugal force is applied to the water collected in the drain groove 51 and the sub-drain groove 52 and the contact surface 3.
Acting on the water that has reached 4, the water in both ditches is drained into each drain 55… 5
56, and the water on the contact surface 34 is drained from each of the drainage channels 55... 55, 56. As a result, all the water is drained from between the drag plate 31 and the contact plate 33, thereby preventing a change in the operation of the drag mechanism 3 due to the water.

Reference numeral 36 denotes a flange provided upright on the entire outer periphery of the friction plate 33. The flange 36 suppresses deflection of the friction plate 33 that occurs when the friction plate 33 comes into contact with the drag plate 31. Specifically, as shown in FIG. 5, when the drag plate 31 comes into contact with the friction plate 33 as the spool 4 slides, forces P1 and P press each other.
1 works. When these forces P1 and P1 act, the friction plate 3
3 tries to bend in the P2 direction, but this bending is suppressed by the flange portion 36. By suppressing this deflection, the same surface pressure is generated over the entire area of the contact surface 35, and the amount of water that enters is reduced. Note that the flange 36 is not limited to the configuration that is provided upright on the entire periphery of the friction plate 33 as long as it has an action of suppressing the deflection of the friction plate 33. May be erected in the building.

The shape, size and number of the drainage channels 55... 55, 56.
As long as the rigidity and drainage efficiency of 3 are not impaired, the shape, size and number thereof are arbitrary.

For example, as another form of the drainage channels 55... 55, 56... 56, as shown in FIG. 5, the through holes are inclined in the direction in which water is drained with respect to the axis of the contact plate 33. No. Drainage channels 55 in this manner 55,5
In the case of 6 ... 56, there is an effect that the water on which the centrifugal force acts is drained smoothly.

The positions of the drainage channels 55... 55, 56... 56 are arranged on the outer side portions 57 and 58 of the drainage groove 51 and the sub-drainage groove 52 as shown in FIGS. No. In this example, the drainage channel 5 is a drainage channel 5 in which the drainage groove 51 and the sub-drainage groove 52 are through holes parallel to the radial center line of the contact plate 33.
56, and the drainage channels 55 ... 55 of the drainage groove 51 are cut out. Drainage channels 55 ... 5 in this way
In the case of 5, 56... 56, there is an effect that the water on which the centrifugal force acts is drained more smoothly.

As another form of the drainage channels 55... 55, 56... 56 of this example, as shown in FIG. One that is inclined is given. The drainage channel 55 thus constructed
55, 56 ... 56, there is an effect that the water on which the centrifugal force acts is drained more smoothly.

The positions of the drainage channels 55 ... 55, 56 ... 56 are not limited to either the bottoms 53, 54 or the outer side portions 57, 58. For example, drainage channels 55 ... 55
Is the bottom 53, the drainage channels 56.
You may make it. (Not shown)

As a fishing reel provided with the drag mechanism 3 having the drain section 5 as described above, there is a spinning reel B as shown in the figure. This spinning reel B
Is a technique proposed by the present applicant in Japanese Patent Application No. 7-148877, and will not be described in detail. However, a drag force is generated when the rotating contact plate 33 comes into contact with the drag plate 31. is there.

That is, when the spool 4 is rotated by paying out the fishing line, the contact plate 3 that rotates integrally with the spool 4 is rotated.
3 generates a centrifugal force, and the centrifugal force acts on the water stored in the drain groove 51 and the sub-drain groove 52 and the water between the drag plate 31 and the contact plate 33, and the water is discharged into the drain passage 55. ... 55,56
... drained from 56. Therefore, similarly to the dual bearing reel A, the drag function is prevented from lowering due to water.

Although the above-described drag mechanism 3 has been described as having two friction plates, that is, the drag plate 31 and the contact plate 33, the present invention is not limited to this structure. A plate-type drag mechanism may be used. The arrangement of the drainage section 5 in the drag mechanism having this configuration can be achieved by forming a drainage groove and a drainage channel in one of the opposed friction plates. (Not shown) The dual bearing reel A
In addition to the spinning reel B, the drag mechanism 3 having two friction plates as described above, or any fishing reel having a multi-plate drag mechanism is applicable. (Not shown)
